Facebook continues charging down the road of political correctness, with blocks imposed on various sites which it does not like: https://www.facebook.com/zuck/posts/10104501954164561
As Zucky himself says: “For example, take the Wall Street Journal or New York Times. Even if you don’t read them or don’t agree with everything they write, most people have confidence that they’re high quality journalism. On the flip side, there are blogs that have intense followings but are not widely trusted beyond their core audience. We will show those publications somewhat less.”
Perhaps this censoring is why teenagers are starting to turn away from Facebook:

In any case, there are apparently tech ways of circumventing Facebook’s attempt to prevent you seeing posts of your favourite site:

I do not need to do this because I live happily without Facebook, but if the bug has infected you, then action may be needed.
